Remarks. Thai (1983) proposed a new subgenus Terrata of the genus Pheretima, and placed the species under the new subgenus. Blakemore (2007a, 2008b) considered it as " species inquirenda ". Material was re-examined and absence of male copulatory pouches and hence placement of the species in Amynthas is confirmed here.
